I rarely trade in them in so digital never bothered me, and for certain games I'll always try to buy them digitally whenever possible.
The other thing is that my PSN account is US based as I originally made it when living with my parents in NJ. Games are $60 in the US and $70 in Canada (no tax in the US as it's digital, and 15% in Canada where I live). So I'm almost paying $20 more to buy a physical copy that ends up being less convenient for me.
That being said, the majority of the games I buy digitally are ones during the flash sales, so I'm rarely spending more than $5 for full games. The only one I've gotten so far this gen is MLB14, though Destiny will be a digital game as I can see myself putting 100+ hours into it easily (put around 200 into BL2, mainly due to co-op, and I'm more excited for Destiny).
